title	How to style my data in Examind ?

1. You have different ways to add a style.
   • You can create a style using a specific data uploaded on Examind (available during the "Add data" process, or if you click on a data in Data tab)

   :align: center
   

   (bottom right of the screenshot)
   • You can crate a generic style (available in the Styles tab)

   :alt: Add style generic
   :width: 100%
   :align: center
   

   Then you need to choose between Vector or Raster style.

Notes :

• It's easier to create a "specific" style for a specified data, because you can see the result directly, and because examind can help you during the creation (it can show the min/max of your data to create a color palette, ...)
• If you know your image (its metadata, its values, ...), you can create a generic style, and use it for multiple data.

In this tutorial, i will work on a specific raster data.

2. In the Style Selection pop up, you can click on Create new style. You will have something like this

3. You can add different rules to your style :
   • Color and Palette (if you want specific color palette) (we will use this here)
   • Group of cells (for vectors data)
   • Dynamic ranges
4. Select Color and Palette, set a name, a title and a description if you want, and click on Symbols tab
5. You will have this interface :

   :align: center
   

6. In Color Model you can choose between :
   • Palette Mode : Selection of a band, to create a color palette
   • RGB Composition Mode : Selection of which band will be used for Red, Green, and Blue
   • Grayscale Mode : Same as color palette, but you will generate a style in grayscale directly
7. Here we will crate a color palette. Select the band you want to use. Examind will fill the min/max values of your data. You can change these values if you want.
8. Select a palette you want

9. Set a number of division (number of colors in your palette)
10. Check "reverse colors" and/or "NaN" if you want. In my case, I have something like that :

11. Click on Generate Palette
12. You will have a preview of your palette. You can change the colors if you want.

13. Click on Back to the rules list, add as much rules as you want, and click on Create the style.
